Title: Switching circuit, inverter equipment, lighting device for discharge lamp and lighting equipment
Inventor: KITAMURA NORIYUKI
IPC: H02M7/537
Filed: 1994-09-29
Abstract: PURPOSE: To make the control simpler and more reliable and reduce the effect of the dispersion of parts by controlling in a predetermined section both negative and positive saturation characteristics of a current transformer and by providing OFF sections between mutual switching by controlling the feedback output. CONSTITUTION: When a base current IB is supplied, switching means 11a is turned on and, after the elapse of a predetermined time, an auxiliary switch 13c is turned on. At the same time, a current transformer 12a is saturated magnetically, an induced voltage of secondary winding 12a2 becomes zero instantaneously, and switching means 11a is forcibly turned off. Since no base current flows to switching means 11b while the auxiliary switch 13c is ON, the auxiliary switch 13c turns off again, and switching means 11b turns on after the base current flows. In this way, an OFF section where both means can be off simultaneously is created between alternate switching of the switching means 11a and 11b and therefore the switching loss and the occurrence of noise can be reduced.

Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To stop an operation of a DC-AC conversion means by changing the frequency and amplitude in outputted current, superimposing a pulse and a message, changing the frequency of a reference signal at arbitrary timing, and detecting the power cut of a power distribution system at that time. SOLUTION: A DC-AC conversion means 12 generates an AC current waveform based on the reference signal which a reference signal generation means 13 generates and supplies it to the power distribution system 3. The frequency is changed to arbitrary one at timing which a timing signal generation means 15 gives. Thus, the output current waveform of the DC-AC conversion means 12 is changed at timing given to the frequency which an arbitrary frequency generation means 14 generates. When the power distribution system is normal, the output voltage waveform becomes similar to the frequency of the power distribution system, but the frequency of output voltage becomes similar to the frequency of output current when the power of the power distribution system is cut. An output voltage detection means 16 detects it and stops the operation of the DC-AC conversion means 12.
